V. E. BEAGLE HOISTING TRUCK Filed Dec. 27, 1922 3 Sheets-Sheet 3spective guide wheels 20 at rear ends of the side members, and aroundsprockets 21 at the front part of the frame, the sprockets being keyedupon a transverse shaft .22, mounted revolubly at the frame, and havingan intermediate sprocket 23 driven by a corresponding; sprocket 24 onthe shaft 25 which is provided with a, hand crank 26 a chain 2?transmitting motion between the two last. named sprockets. It isunderstood that the chain 19 is secured to the carriage in any suitablemanner, so that movement of the crank in one direction will move thecarriage forward, and reverse operation of the crank will move it rearwardly. v

Each carriage comprises an upper box portion 27, o n at the front andrear and of substantia ly rectangular form, being of a dimension toreceive loosely the members 11,

these members being shown as channel memfaces being suitably here withside flanges projected downwardly. The box extends sullieiently abovethe sic e member to permit the mounting of boxsupporting rollers-28transversely therein on shafts 29- which .are extended through the box.The rollers are of a size to beentirely enclosed within the box, so thatthey will not become fouled nor have clothing or objects entan ledtherein,readily. The side. memberso the box 27 are extended downwardlyand inwardly a distance beneath the side members 11, as at 30 and thendownward as at 31 stance, their opposed channelled or grooved thereinand properly in parallel relation a and raised to receive engage inrespective sides of a crossbar 33 of channel 1ron, the ends 32 of whichare projected upwardly between the members 31 of respective carriageszontallv for the full width of the truck, a

with respect to the side members,by reason of the lar it is pose: is touse in itsattachment'. It is not essential that the forward-edge of theyoke be inclined, necessarily, and this may be varied as desired.

Each carriage member is formed with wing plates 35, which-extendrearwardlyf from the members-31, and are=also"joined integrally to theparts 30 and the lower parts of the sides of the box 18. The wingmembers are formed in such manner that when the carriages are at therear limit of lower side of the and extended hori-.

The carriages are securelyfixed upon the cross bar 253, and there is thus formed a mutual rigidconnection between the yokcs which in itself also insures their,retention by its own strength, in fixed relative relation. The wings3:") are shown to have asiight taper toward the,rear ohthe inner side.so as to facilitate entry of the yoke 17 therelietwejcn', and they arealso shown slightly thicker at the bottom than'at the top, as may besee-11 in Fig.9 so t-liat snug fitting engagement with the yoke 17 willbe insured; The taper andfthickening however, may be varied or dispensedwith; as found desirable.

From the rest the rod is extended forwardly and upward and issecured in an anchora e 39 on the underside of the truck frame.ftearwardly of the rest 38 this rod lies just inwardly of the path ofthe carriage 18, and insures the proper positioning of. the truck whenbeing backed into position for loading, so that when the carriage ismoved rearwardl it will not strike the load and be blocke The mountingof the load sustaining element may be constructed to truss the side'members of the frame in other ways, arid in Figures 9 to 14 inclusivethere is illustrated a heavy duty trailer truck in which the particularconstruction of the rirst form might not be suitable. In this instance,the frame side members 40 are truss elements including top and bottomstringers 41 connected by diagonal Hats 42. Adjacent the rear end ateach side a heavy fitting 43 is secured between the two stringers havingoppositely projected stub axle shafts 44 upon which respective wheels 45are mounted at the inncr and outer sides of the member 40 respectively.At the rear ends of the frame. hangers 46 are provided depending andadapted to receive a removable load supporting bar 47 insertiblctherethrough.

At the forward end of this truck an arch 48 of channel iron is providedhaving its side members bolted to the outer sides of the? frame just alittle back of the extreme forward end of the frame. This arch is bracedby diagonals 49. from the front cross mem': her of the frame. A chainhoist 50 is mounted centrally of the arch which may be used to lift theforward end of the load The lower stringer 41 of the frame is in--clined upwardly at the forward end, as

shown in Figs. 9 and 11, and the entire side member atthis part is,curved inwardly, as shown in Figs. 10 and 11. This construction ivesample clear way mder theframe at 51c forward part for th mounting ofcomparatively large front wheels 51 which may e carried in adirigiblmmounting 52 following any approvcd construction. The mountingincludes a forwardly projecting draft ton us 53 by which'the truck maybe towed. )ther construction and other means for moving hetrucka..maybe; adopted readily. I a

It s iould be noted that the wheels 45 are s aced sufficiently from theside members of t 0 frame to permit the carriages 54 of a load support55 to pass therebetwen. The

- load supportingmembcr comprises a channel member hung from thecarriages, which comprise flat plates bent to form a snug boxing for therespective side members 40. The boxing extends sufiiciently above theframe "to accommodate rollers 56,, as seen in Fi'g- 13. The member 55may be moved by an adaptation of the means before described for shiftingthe load carrying element, or other means may be employed.

In Fig. 15 another embodiment of the hcavy duty truck is illustrated, inwhich upper and lower elements are combined in the side members of theframe, in a slightly different manner, and single wheels are mountedoutward of each side of the frame.

In this instance, I have illustrated a method of mounting the sidemembers of the frame in such manner that the load carrying bar may bemoved rcarwardly past the wheel truck members, and this may beaccomplished whether there is one or two longitudinal structuralelements in each side member of the frame. In the present instance,there are illustrated two longitudinal I-beams (it) comprising the sidemembers of the frame, carried upon spindle castings 61, mounted in heavyrubber tired wheels 62 which may be of any usual construction. Thespindle forgings including an upper inwardly extending bracket ($3. uponwhich one beam 60 is mounted, and over which a bracing arm is provided,against which the web of the be 60 is secured. Beneath the bracket 63 adownwardly extending arm 66 is formed on the spindle member at the lowerend of which a bracket 63' is provided, over which there is a brace 65'to which the lower beam 60 is secured, as shown. The arm 66 isproportioncd and inclined so that there is a clearance-between it andthe upper part of the beam 60, and the forging is also proportioned toreceive the two beams with a sufiicient clearance from the wheel 62.Carriage elements 67 are formed integrally with a load carrying bar 33,as shown, al though those parts may be separately constructed ifdesired. The cariage elements have two similarly formed outwardlyprojected brackets 68, one overcach of the beams 60, and includingdownward projected parts within which are mountcd rollers 69, thebrackets 68 engaged under the upper outcr flanges of the beams 60whereby secure and rigid relation is established between the' carriageelements and the side members of the truck frame. In this way, thetorque developed by a load, tending to incline the wheels 62 inwardlytoward the top, is resisted by the carriage element and cross bar 33'.

For a ready understanding of the manner of .use of this truck Figures 16to 20 are presented, and the operation described a plies/to all forms ofthe truck. A load 0 eing upon the ground, the truck is drawn to aposition with the load in line with and adjacent the rear open end ofthe frame. Therload carrying element being moved to the forward limit ofits movcmentupon the frame it is backed into position as in Fig. 17.Such hoist device as may be employed lltl 18 until the load carryingelement may be moved rearwardly of the center of gravity of the load,and preferably to its rearmost position, as in Fig. 19. The forward endof the load is then lowered, when its intermediate part will be brou htinto bearing upon the load support, an pivoting there the rear and willrise. The load is'in this way adjusted so as to clear the round proper];and the truck then moved with the load thereon.

hat is claimed i 1. In a truck of the character described, a truck frameproper, a load sup orting member movable thereon, said frame aving wheelmountings thereon at opposite Sides, said load supporting member andwheel mountings having parts operative to interlock when the loadsupporting member is in load supporting position.

2. The device of claim 1, in which the wheel mountings include partsbelow the frame, and the load supporting member includes parts slidableon the side members of the frame and connected by a rigid member, andhaving projected parts to receive and engage positively against lateralmovement, the said parts of the wheel mounting below the frame.

8. The device of claim 1, in which the load supporting member includescarriage elements on the side members of the frame and a connectin rigidmember, the wheel mountings incln e vertical members, and the carriageshave rea'rwardly projected win flanges spaced and disposed to snugly anpositively receive and on age the vertical members against relativeateral movement.

4. In a truck-of the character described, a U-shaped frame, wheelmountings at the rear of each side member including vertical membersrigidly fixed upon the frame, car-- riage elements slidablelongitudinally on the- :frame having a. rigid connecting bartherebetween and fixed thereto, said carriage elements having rearwardlyprojected plates spaced to firmly receive and engage therebetween thesaid vertical members to prevent relative movement thereof. 7

5. In a truck, an open ended frame, suporting wheels and mountingstherefor, a ongitudinally movable load carrying element on the opposedmembers of the frame constructed and arranged to form a rigid trussbetween the wheel mountings at opposite sides of the truck adjacent theopen end of the frame.

In testimony whereof I have aflixed my signature.
